Data retention device
The present disclosure relates to a data retention device designed for security of digital classified information. In the data retention device, a power source component is first activated by a fingerprint switch. When a data plug of a dedicated storage module and a data socket of an encryption module are connected with each other, a locking element in the encryption module is fixed at a locking hole in the dedicated storage module and the encryption module is electrically connected to the dedicated storage module through the data socket. Then, with an external component of the encryption module electrically connected to an external device, classified information is accessed, encrypted in the encryption module and saved in the storage element.

The present disclosure relates to a data retention device for encryption of data, particularly a dedicated storage module saving classified information and physically removed from the data retention device, such that classified information encrypted by an encryption module is accessed from the dedicated storage module with an external component electrically connected to an external device.
2) Description of the Prior ArtWhen the personal cloud is widely used in a private network, centralized management is available to private storage devices gradually and centralized data management and backup is provided by independent network storage devices which are connected to the private network; however, the privacy issue of personal data is exposed correspondingly.
The patent documentations with respect to storage systems are shown as follows:
As shown in Japanese Patent JP 2002-236380, a data retention system provides data saved in a user's terminal and accessed through the internet to the user or other users such that the data are available to a plurality of terminals. For all types of terminals owned by users, the data retention system is equipped with a server comprising a unified connection interface through which a user's terminal and a service provider's data management unit are connected via the internet. Moreover, data saved in a FTP server is processed for the data retention system during data format conversion. When data/files in the data retention system are used by users through different types of terminals, the data/files should be processed during data format conversion for applications in users' terminals and further transmitted to users' terminals.
As shown in R.O.C. Patent TW 526643, a data access and control system and a method thereof rely on the secret sharing principle to divide a master key into n sub-keys which are given to n sub-key owners. Then, m sub-keys (1<m<n) are obtained by a reorganization utility of the master key based on the secret shared by sub-key owners; the master key can be reorganized according to the (m,n)-threshold programme. Finally, classified data to be accessed by the data access and control system can be encrypted or decrypted based on the master key. Accordingly, m sub-keys should be attained for reorganizing the master key before data in the data access and control system is modified or accessed; privacy and security of data in the data access and control system is guaranteed. Furthermore, when a sub-key owner left office or was transferred to another post, a sub-key owned by the sub-key owner rather than the master key is changed for reorganization of the master key and least influence on accessing ciphertexts due to change of a password.
European Patent EP 12178889.7 discloses a method to safely access a service inside a defined trustable environment. As shown in EP 12178889.7, there is at least a network component existing in the defined trustable environment and having a password saved internally. When a user device is introduced into the trustable environment, the user device will contact the network component to receive the password saved in the network component. Then, the password is transmitted to the service by the user device and checked with a matched password saved in the service for activation of the service.
